This invention relates particularly to a mounting for supporting and controlling the opening and closing movements of an individual sash or a plurality of sashes or other analogous inclosures.

An object of the invention is to provide a mounting for sashes that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation and facility and Convenience in use and general eiiiciency.

A further object of the invention is to provide a mounting' or mountings for supporting a sash or a plurality of sashes or other analogous inclosures, within an enclosing frame, for controlling and regulating the opening and closing movements of the sash or sashes I'and having means thereon to regulate the friction of the moving parts of the sash mountings.

A still further object of the invention is to provide in combination with a window iframe and plurality of sashes, of means interposed between the sashes and frame to maintain the sashes in any desired openedor closed position against wind pressure and the like.

Other objects and advantages will appear as this description progresses.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

This invention relates to the pivoting of a pluralityy of window sashes, on the opposite stiles of each sash, at a pair of corresponding points, to slide shoes which are slidably retained in independent guides on opposite sides of the Casement or window frame and connecting all of the sashes together by coinmon support arms, connected at corresponding points on opposite sides to each of the sashes, each of said support arms being adjustably pivoted to the window frame.

In detail, the construction illustrated in the drawings includes a window frame composed of a sill 1, stool 2, and side jambs 3 connected across the top by the lint-el fl, together withthe usual stops 5 or other. weather proofing finish mounted on the interior of the jambs, stool and lintel.

Each of the jambs 3 of the frame are either :.hanneled to form guideways 7 or are provided with guideways thereon which said guideways are arranged in a relatively vertical position and in alignment with each other on the opposite side jambs. The stops 5 are secured to the ambs 3 to partially cover the guideway 7 so as to finish the interior of the window frame in accordance with standard practice.

A plurality of pairs of slide shoes 12, consisting of met-al Vmembers with flange ends 11, are slidably retained in each of the guide ways. A f plurality of separate sashes 8, 9

and are arranged in the window frame to cover the entire area thereof and each sash is supported on its opposite stiles, at a paii` of corresponding points, to slide shoes which are slidably mounted in the opposite guideways. The sash V8 atcorresponding points on its opposite side stiles and adjacent an end thereof, is pivotally connected by the pivots 13 on the sash plate 19, to the slide shoes 12 in the opposite guideways. Similarly, each of t-he sashes 9 and 10 at corresponding points on their opposite side stiles, and adjacent an end thereof, are pivotally connected by the pivots 13 on the sash plates 19 to slide shoes 12 on the opposite guideways. r)The slide shoes 12 support each of the sashes 8, 9 and 1.() for sliding movement in a vertical direction and also permit the sashes, individually or in unison, to be swung outwardly from a closed vertical position to a substantially reversed position.

Each of the sashes are operatively supported in the window frame in either the closed vertical position, or in an open position or in a reversed position, by support arms 24. All of the sashes are supported by common support arms, there being a. supp rt arm connected to one side of all of the sashes and a similar support arm connected to an opposite side of the sashes. Each of the sash support arms 24 are pivoted at 25 to a plate 26 on the opposite stiles of the sash 8, at a point between the horizontal center of said sash and the free end thereof. rThe same support arms are pivoted at 27 to a plate 28 on the opposite stiles of the sash 9 at substantially the horizont-al center thereof, and said arms are pivoted at 29 to a plate 30 secured to the sash 10 between the horizontal center thereof and head rail thereof, whereby the opposite support arms 24 are connected to all of the sashes.

The lower end of each cont-rol arm 24 is pivoted at 31 to a bearing plate 32 arranged at the lower end of the guideway 7. Each bearing plate 32 is secured'by screws 33 to the opposite sides of the window frame. The plate 32 is provided with an arcuate slot 34 therein, cut on a radius struck from the pivotal aXis of the pivot 31, and a fastening screw is arranged in each arm 24, to pass through the slot 34 in each bearing plate 32.

A yieldable or resilient friction plate 36 has an end thereof secured to the under sido arm of the pivot 31. The friction plate 36 is coextensive with the arm 24, and the free end of the friction plate 36 is tapped to be engaged by the threaded end of an adj ustins` screw 35. By tightening on the screw 35, the control arm 24 and the friction plate 36 are drawn tightly against the opposite faces of the bearing plate 32 and frictionally engaged therewith. As the adjusting screw 35 is loosened the friction plate 36 tends to draw away from the under side of the bearing plate 32 to diminish the frictional resistance between the arm 24, friction plate 36 and the bearing plate. The adjusting screw 35 functions as a regulatory medium by means of which the friction Aon the control arm 24 may be increased or diminished so as to control movement of the sash mounting. lhe screw 35 controls the entire operation of the sash mounting, making it possible to hold the sashes in any desiredposition without fear that wind pressure or the like will cause the position of any sash or plurality of sashes to be changed. A sash or plurality of sashes supported upon my sash mounting does not require any auxiliary or additional mechanism to hold any single sash or plurality of sashes in a closed or opened or partly opened or reversed position. The manner in which the support arms are secured to all of the sashes permits of all said sashes to be opened or closed simultaneously and in unison.

The sashes illustrated in the drawings, when operatively installed in a window frame, are opened best by manually pushing outward upon the lower` rail of any one of the sashes. As the lower end of the sash is moved, the support arms 24 are swung outwardly, causing the sashes, not pushed, to open outwardly, in accordance with the movement imparted to the manually moved sash. Movement of the free end of one sash causes theV opposite enels of all the sashes on the slide shoes to slide in the guideways and the supporting arms to swing relative to the frame. The construction of the sash mounting is such that all of the sashes mounted thereon may be substantially reversed in the window frame simultaneously or independently, so as to present the outer surface of one or more of the sashes to the interior of a room to facilitate washing.

ln order to hold the sashes in a selected open position, Iv have pivotedv a stop arm 40 on a pivot 41, mounted upon a plate 42 that is secured to one of the side j ambs. The plate 40 is pivoted at one end so that the opposite end of the said plate is free to follow any opening movement of the sash'to which it is related. A stop pin 43 is mounted on the plate 42, to limit the downward pivotal movement of the stop 40, while a pin 44 limits the pivotal movement of said plate in an opposite direction. l/Vhen the sashes are swung into the open position as shown in Fig. 1, a stop arm 40 will swing down automatically into t-he position shown in Figs. 1 and 3, the free end of the plate 40 engaging the face of the sash, and stopping the downward sliding movement of the head rail of the sash. By reason of all of the sashes being connected to a common supporting arm, whereby all of the sashes operate in unison, the said stop plane 4() causes all of the sashes to be stopped in a selected open position.

In the modified form of the invention leo msm-os shown in Figs. 8 to 12 inclusive, I provide the window frame comprised of the sill 50, stile 51, and side jambs 53 connected across the top by a lintel 54, together with the usual finishing material 55. Each of the Jambs 53 are provided with guideways 57 therein, the same as in the preferred form of the invention heretofore described. A plurality of pairs of slide shoes 62, consisting of met-al members having flanged ends 61, are slidably retained in each of the guideways 57. A plurality of separate sashes 58, 59 and 60 are arranged in the window frame to cover the opening therein, and each sash is supported on its opposite stiles, at a pair of corresponding points, to a pair of slide shoes which are slidably mounted in the opposite guideways. The sash 58, at corresponding points on its opposite side stiles and adjacent an' end thereof, is pivotally connected by the pivots 63 on the sash plate 69 to the slide shoes 62 `in each of the opposite guideways. Similarly, each of the sashes 59 and 60 at corresponding points on their opposite side stiles, and adj acent an end thereof, are pivotally connected by pivots 63 on the sash plates 69 to slide shoes 62 on the opposite guideways. The slide shoes 62 support each of the sashes 58, 59 and 60 in the window frame.

The sashes 58 and 59 are supported by common support arms 74, there being a separate arm connected to one side of each of t-he sashes 58 and 59, and a similar support arm connected to the opposite side of said sashes. Each of the sash support arms 74 are pivoted at 75 to a plate 76 on the opposite stiles of the sash 58 at a point between the horizontal center of said sash and the free end thereof.

The same support arms are pivoted at 57 to v-a plate 57 on the opposite stiles of the sash 59 at substantially the horizontal center thereof. The lower end of each control arm 54'is pivoted at 81 to abearing plate 82 arranged vat the lower end of the guideway 57, each bearing plate 82 being secured at opposite sides of the window frame. Each plate 82 is provided with an arcuate slot 84 therein, cut on a radius struck from the pivotal axis of the pivot 8l, and a fastening screw 85 is arranged in each arm 74 to pass through the slot 84 in each bearing plate 81. A friction plate 86, below the plate 82, is secured at one end to the under side of the pivot 81 and the free end of the plate 86 is tapped to be engaged by the threaded end of an adjusting screw 85. 'lheadjusting screw 85 functions to move the plate 86 relative to the plate 82 and as a. regulatory medium by means of the friction created thereby, the control arm 74 may be regulated as desired to control movement of the sash mounting.

A link 45 is pivotally mounted on the pivot 63 that connects the slide shoe 62 to the sash 59, there being one of the links 45 arranged on each of the opposite sides of the sash at corresponding positions thereon. The opposite ends of each of the links 45 are pivotally connected at 46 to the opposite side stiles of the sash 58. The links 45 are pivoted to the respective sashes 58 and 59 to lie exactly parallel to the control arms 74 that support the said sashes 58 and 59. The links 45 are offset so that when the sashes 58 and 59 are arranged in the vertical closed position, said links will not interfere with the supporting arms 74 moving into the closed position. Likewise, the links 45 lie relatively close to the stiles of each of the sashes 58 and 59, whereas the control arms 74 are secured to the sashes 58 and 59 on U-shaped brackets 76 and 57 respectively, which yproj ect a slight distance out from the edge of the sash stiles. The links 45 and the support arms 74 swing in different planes to avoid any interference between them in operation, and the mediate portion of the links 45 is offset relative to its opposite ends to avoid any possible conict with the control arms 74. The links 45 keep the sashes 58 and 59 in a predetermined spaced relation at all times, and cooperate with the arms 74 whereby the sashes 58 and 59 may. be moved in absolute unison into any selected open or closed position.

The modified form of the invention differs from the preferred form in that the lower sash 60 is not pivotally connected to the control arms l24, but said lower sash is carried by its own individual supporting arms. Each side of the lower sash 60 is provided with a support arm 47 pivoted at 79, to a plate secured to the side of said sash 60 'between the horizontal center thereof and the head rail thereof. The lower end of the support arm 47 is secured to the pivot 81 on the bearing plate 82, which, said pivot 81 also supports the control bars 74 that supports the sashes 58 and 59. The ad'usting screw heretofore described, also unctions as the regulatory medium by means of which the friction on the control arm 47 may be increased or diminished so as to control movement of the mounting of the lower sash 60, and its supporting mechamsm.

Each of the supporting arms 47 are arranged between eaeh supporting bar 74 and the side stile of the sash, whereby the lower sash 60 may be opened and closed independently of the upper sashes 58 and 59, or the upper sashes 58 and 59 may be opened and closed independently of the lower sash 60. However, in order that all of the sashes 58, 59 and 60, may move in unison if desired, I have provided a spring arm 90, that. is secured at 91, to the inside face of each of the control arms 47. The opposite end of the spring arm 90 is provided with a U- shaped socket 92 therein, that is adapted to extend completely around the control arm 47, from the under side thereof, and to pro# ject beyond the outside face thereof into the path of travel of the sash supporting arms 74. Each socket 92 Will thus spring into engagement with its corresponding control arm 74, whereby the control arms 7e and t7 may be made to move in unison.V The socket 92 will connect the control arms 74 and e7 together, whereby all of the sashes 58, 59 and 60 may be opened, and then, if desired, the sockets 92 may be disengaged from the support Varms 7e, whereby the lower sash 6() may be closed, or the upper sashes 58 and 59 may be closed, or vice versa. As it often happens in ventilating rooms and buildings, conditions may be such that. selective ventilation in either the lower or upper part of the room is required, and my mechanism herein described, provides a multiple sash supporting mechanism in which one or more sashes of a group may be disconnected from the group' of sashes and operating mechanism therefor, and opened or closed While in the disconnected position. The socket 92 that is used to connect the support arms 47 and 74 together, is operated manually in effecting disengagement of the arms, Whereas to' vengage the supportarms 74; With the sockets 92, I have provided a rounded edge 93 on one side of each socket 92 Which Will permit of an automatic entry of the arm 74@ into the socket 92.

Although have shown and described a particular method of and apparatus for mounting a plurality of sashes Within the Window frame, whereby oneor more sashes of the group may be disassociated therefrom and operated independently thereof, it is to be understood that I do not limit myself to the particular form of the mechanism shown.

AlthoughV I have shown and described a mounting for a plurality of sashes with particular reference to Wooden sashes, it is to be understood that it Would be clearlyWit-h in the scope of the invention to utilize such a sash mounting on different kinds of Windows and transoms, and also that the sash mountings can Lbe applied to a easement.
